So far, most systems based on this 'direct approach' have not been energetically competitive. However, the balance changes as soon as some of the hydrogen in such PEC cells is used in-situ for a catalytic hydrogenation reaction, resulting in the co-production of chemicals used in the chemical and pharmaceutical industries. The energy payback time of photoelectrochemical 'green' hydrogen production can be reduced dramatically, the study shows.

The device employs a quasiperiodic nanoscale pattern, meaning most of it is an alternating and consistent pattern, while the remaining portion contains random defects that do not affect its performance. The fabrication process makes use of self-assembling nanoparticles, which form an organized material structure based on their interactions with nearby particles without any external instructions. Thermal energy harvested by the device can be transformed to electricity using thermoelectric materials.

The new method splits the seawater directly into hydrogen and oxygen -- skipping the need for desalination and its associated cost, energy consumption and carbon emissions.
